Accelerlist allows you to list products on both marketplaces, Amazon and Ebay.
So if your product gets sold on either of the platforms, it immediately gets removed from the other platform if there is only a single item instead of multiple quantities of it.
Ex: If you've listed an Item A with 3 quantity and the item is sold on Ebay twice, then the quantity shall be changed to 1 on Amazon.
If you have just 1 unit of an item listed on Ebay and Amazon and it is sold on either platform, then the quantity changes to zero, and the listing gets removed from the other platform.
